Depends on the power level you're loading them to.

Speer recommends seating 200 and 230 grain non-cannelure bullets deep into the case and crimping over the shoulder for SWC's or on the nose for RN's. Of course that requires different data, so be careful.

The most important factor is good bullet tension. Use an absolute minimum amount of flare and case mouth expansion so the case gets a good grip on the bullet. If you get good bullet tension is it usually enough to hold the bullets without crimp for plinker loads.
